VCDirIsWritable

public VCDirIsWritable(com.jgoodies.binding.PresentationModel<E> model,
                       String propertyName)

creates a constraint, that checks, whether the value of the given property is a writable directory

Parameters:

model - - the presentation model, that manages the bean

propertyName - - the name of the property containing the path of a directory

VCDirIsWritable

public VCDirIsWritable(com.jgoodies.binding.PresentationModel<E> model,
                       String propertyName,
                       PropertyCondition<E> pc)

creates a constraint, that checks, whether the value of the given property is a writable directory. PropertyCondition is a construct to check, whether validating should be bypassed or not.

Parameters:

model - - the presentation model, that manages the bean

propertyName - - the name of the property containing the path of a directory

pc - - a PropertyCondition used to bypass the validating. If property condition matches, it means no validation will be performed and if the property condition fails the validating will be performed.
